How one might be cast as Captain Bligh? (6)
I believe the answer is:
adrift
'as captain bligh?' is the definition.
I can't tell whether this definition defines the answer.
'how one might be cast' is the wordplay.
'how one might be' becomes 'a' (I can't justify this - if you can you should believe this answer much more).
'cast' becomes 'drift' (synonyms).
'a'+'drift'='ADRIFT'
Can you help me to learn more?
(Other definitions for adrift that I've seen before include "Afloat without steerage" , "not settled" , "'Floating without direction, not tied up (6)'" , "Wandering aimlessly" , "Purposeless" .)
